APPLICATION OF GUIDEWAY ROUGHNESS POWER SPECTRAL DENSITY AS A MANAGEMENT TOOL
Ground surface vehicles such as trucks or railway cars can be considered as mechanical systems suspended on vibrating wheels. The source of vibrational energy is the roughness in the roadway or the guideway. A portion of the vibrational energy is transmitted through the vehicle suspension system and to the passengers or lading inside the vehicle. The magnitude of the transmitted energy and its frequency content depend on the roughness of the surface, the speed of the vehicle, and the mechanical characteristics of the suspension system. If the roads and guideways are categorized by the Power Spectral Density (PSD) of their surface roughness, the amount of vibrational energy can be predicted if the speed and the characteristics of the vehicle suspension system are known. Conversely, if a safe limit of the vibration has been established for a particular lading, management can render a cost effective decision on guideway maintenance, speed practices, and vehicle design from knowledge of the PSD characteristics of a proposed route.
